The Cesarska Gora mountain stands tall and proud as it overlooks the town of Klanjec – from the River Sutla in the west to Cesarska Ves in the east. The highest peak of Japica is 511 m above sea level. Since 1949, together with the neighbouring Risvička Gora and the River Sutla, it has been protected as a natural rarity, i.e. a significant landscape, primarily due to its ecological, cultural, and historical significance. The area of Cesarska Gora is covered by a forest of beech, sessile oak, and common hornbeam and a forest community of downy oak and hop hornbeam. The mountain provides habitat for many protected and rare endangered plants, including the Croatian iris, the Croatian carnation, the Carniolan lily, the Pannonian clover, and others. The importance and value of Cesarska Gora are also reflected in the presence of numerous other species. The thriving environment is home to 71 species of birds, 68 species of diurnal butterflies and 522 species of moths, 37 species of lichens, 30 species of saproxylic beetles, 20 species of mammals, seven species of reptiles, and many other species.
Members of the nobility also appreciated the beauty of Cesarska Gora, as evidenced by the remains of the Cesargrad fortress, which dates back to the 13th century. During the Croatian–Slovene Peasant Revolt of 1573, the fortress was pillaged and set on fire.
For nature lovers, there is also a 4.5-kilometre circular eco trail around Cesarska Gora. Along the trail, there are educational panels with information about the flora and fauna, both today and in the past, as preserved in the fossil record, in addition to other interesting things in this area. At the foot of the peak is the Cesargrad Mountaineering Lodge, easily accessible by several marked hiking trails.
